Automatic balancing system for internal centering of large rotating moving parts

Abstract

The invention discloses an automatic balance system for centering of large rotating parts. The balance system is provided with a base and a radial balance mechanism. The radial balance mechanism is installed on the base, and the base is fixed on the The radial balance mechanism is provided with at least two groups of radial balance components, and the radial balance mechanism is respectively located on both sides of the raceway of the rotating moving part; the radial balance component includes a radial balance pendulum rod and support rollers, the support rollers include at least two groups, each end of the radial balance swing rod is provided with at least one set of support rollers, the support rollers are installed on the radial balance swing rod, and the support rollers can be opposite to each other Rotate toward the balance pendulum, the radial balance pendulum is not fixedly connected with the base, and the radial balance pendulum can rotate relative to the base. The invention is used for the centering automatic balance system of the large rotating moving parts, and can improve the service life of the rotating moving parts and supporting rollers.

Description

technical field [0001] The invention relates to the technical field of storage and transportation of bulk materials, in particular to an automatic balancing system for internal centering of large rotating moving parts. Background technique [0002] As the mainstream equipment for bulk material reclaiming operations, portal (bridge) bucket wheel machines are widely used in storage yards. The bucket wheel mechanism is its core component, and the rolling ring kinematic pair for installing the wheel bucket and performing the reclaiming operation is its core. For a long time, the design optimization of its structure has always been a persistent topic. [0003] In the prior art, the structure of the rolling ring support system of the bridge type (gantry type) bucket wheel mechanism has the following advantages and disadvantages: [0004] (1) The radial direction of the rolling ring is restrained and positioned by a total of eight support rollers up and down. The eight supportin...

AI Technical Summary

Problems solved by technology

The eight support rollers are installed independently, and due to the limitation of the structure, it is difficult to guarantee the accuracy of the mutual space position

[0005] (2) The horizontal installation accuracy of the rolling ring is determined by the 4 upper support rollers. In actual working conditions, since the bases of the 4 upper support rollers are all installed on the welded structural parts, in the manufacturing accuracy, working stress, temperature and other environments Under the influence of these four upper support rollers, they cannot fully guarantee the spatial precision (coincident degree of axes, parallelism of end faces) of each other and the rolling surface of the raceway of the rolling rings, that is, they cannot meet the requirements of the rolling rings. The rolling surface of the raceway is supported by a balanced force, so that the machine can only work in the "usable" state

[0007] Based on the above points, 1) The usual on-site phenomenon is that the rolling surface of the raceway of the rolling ring and its supporting rollers are prone to wear and damage, which requires daily maintenance and has a short service life (belonging to regular spare parts), which increases the production cost of the equipment user. And the equipment will produce vibration and noise during operation

2) The adjustment workload of the equipment is heavy during installation or maintenance
